South Korea prepares to test first domestic space rocket

Texas News Today

Soul South Korea was preparing to test-launch its first domestic space rocket on Thursday. Officials say this is an important step towards taking the satellite launch program forward.

If weather and other conditions are met, the three-stage Nuri rocket is expected to be launched around 5 p.m. (0800 GMT), delivering a dummy payload (1.5 tons of stainless steel and aluminum blocks) to orbit 600 . was there. 800 kilometers (372 to 497 mi) above Earth.

South Korea’s Deputy Science Minister Yong Hong-taek told reporters that the launch was originally scheduled an hour earlier, but was postponed because engineers needed more time to check some valves in the rocket. . he said. He said no problems were immediately detected, but that he could advance the launch in response to wind and other conditions at the planned timing of the explosion.

Engineers completed a 47-metre (154-foot) rocket launch Wednesday night on a small island off the south coast at the launch pad of the nation’s only spaceport, Naro Space Center.

After relying on other countries to launch satellites since the early 1990s, South Korea is now set to become the tenth country to send satellites into space with its technology.

Officials say such capabilities are critical to the country’s space ambitions, which include plans to send more advanced communications satellites and acquire military intelligence satellites of its own. The country also wants to send a spacecraft to the moon by 2030.

The Nuri is Japan’s first space launch rocket built entirely with indigenous technology. The three-stage rocket is equipped with five 75-ton class rocket engines located in the first and second stages.

Scientists and engineers at the Korea Aerospace Research Institute plan to test Nuri further, including another launch using a dummy device in May 2022, before testing the actual satellite.

South Korea had previously launched a space launch rocket from Naro Spaceport in 2013. It was a two-stage rocket made primarily of Russian technology. The launch came after years of delays and a series of failures. A rocket named Naro reached the desired altitude in the first test in 2009, but was unable to put the satellite into orbit and exploded shortly after takeoff in the second test in 2010.

It was unclear how North Korea, which has been accused in the past few years of using its space launch efforts to develop long-range missile technology, would react to Thursday’s launch.

North Korea was sensitive to rising South Korean defense spending and efforts to build more powerful conventionally armed missiles while emphasizing the expansion of its nuclear and missile programs.

North Korean Prime Minister Kim Jong-un accused the United States and South Korea of ​​”destroying stability and balance” in the region with allied military activities and US-led “excessive weapons manufacturing” in Pyongyang’s rubber last month. Delivered in a speech of India Congress. . .. in the south.

The Nuri is powered by a liquid propellant that needs to be refueled shortly before launch, but the Koreans plan to develop a solid-fuel space launch rocket by 2024.
